MenuScrollView

Create a paging swappable menu, easily customizable, with item interactive outside of bounds.

How To Get Started

Just add "MenuScrollView.h" and "MenuScrollView.m" into your xcodeproject. Don't forget to import it wherever you need them :

#import "MenuScrollView.h"

Wheter you use a nib or just hard code your user interface, you just need to create a new view of type MenuScrollView. Then, you only need to add items to your menu:

// Add items to the menu
[self.menuScrollView addItemWithTitle:@"Menu item 1"];
[self.menuScrollView addItemWithTitle:@"Menu item 2"];
[self.menuScrollView addItemWithTitle:@"Menu item 3"];
// and so on

Delegate Methods

The MenuScrollView comes with a delegate protocol in order to handle user interaction with the menu. Two optional methods: -menuItemPressed:(UIButton *)item atIndex:(int)index; -menuMovedToItem:(UIButton *)item atIndex:(int)index; Thanks to those two methods you can actualize your interface or trigger actions when the user changes the menu item selected:

#pragma mark MenuScrollView Delegate methods

// Handle user selecting new menu item
- (void)menuMovedToItem:(UIButton *)item atIndex:(int)index {
    
    // Update text label depending on menu selection
    self.textLabel.text =  [NSString stringWithFormat:@"Menu item selected : %@", item.titleLabel.text];
    [self.textLabel sizeToFit];
}

// This behavior is less likely to be used. It is used when a menu item on focus is touched. It's just here in case someone may find it useful...
- (void)menuItemPressed:(UIButton *)item atIndex:(int)index {
    self.textLabel.text = item.titleLabel.text;
   [self.textLabel sizeToFit];
}

Usefull methods

Manually change menu focus on item, with animation or not:

``` objective-c // Set/Move the menu to desired item // Great for initialization or to switch menu item automatically [self.menuScrollView moveMenuScrollViewToIndex:1 animated:NO]; ```

Get menu items for manipulations or customizations:

``` objective-c

// Access each menu item for customization or extra manipulation for (UIButton *item in self.menuScrollView.itemsCollection) { // Customise view as you want [item setTitleColor:[UIColor colorWithRed:81/255.0 green:188/255.0 blue:197/255.0 alpha:1] forState:UIControlStateNormal]; }

// OR

// Access a specific item in the menu for customization UIButton *menuItem = [self.menuScrollView getItemAtIndex:4]; [menuItem setBackgroundColor:[UIColor redColor]]

<p>Any suggestions are welcome ! as I am looking to learn good practices, to understand better behaviors and Objective-C in general !
Thank you.</p>
